  2. Sprag clutch - Wikipedia

    en.wikipedia.org/wiki/Sprag_clutch

    One-way bearing combining sprags and bearing rollers in one race Sprags jam when driven and slide when in reverse. A sprag clutch is a one-way freewheel clutch.It resembles a roller bearing but, instead of cylindrical rollers, non-revolving asymmetric figure-eight shaped sprags, or other elements allowing single direction rotation, are used.

    This is an accepted version of this page This is the latest accepted revision, reviewed on 31 December 2024. Mechanical device that connects and disconnects two rotating shafts or other moving parts For other uses, see Clutch (disambiguation). Friction disk for a dry clutch A clutch is a mechanical device that allows an output shaft to be disconnected from a rotating input shaft. The clutch's ...

  4. Torque converter - Wikipedia

    en.wikipedia.org/wiki/Torque_converter

    The loss of efficiency as the converter enters the coupling phase is a result of the turbulence and fluid flow interference generated by the stator, and as previously mentioned, is commonly overcome by mounting the stator on a one-way clutch. Even with the benefit of the one-way stator clutch, a converter cannot achieve the same level of ...

  5. Freewheel - Wikipedia

    en.wikipedia.org/wiki/Freewheel

    Freewheel mechanism Ratcheting freewheel mechanism (van Anden, 1869). In mechanical or automotive engineering, a freewheel or overrunning clutch is a device in a transmission that disengages the driveshaft from the driven shaft when the driven shaft rotates faster than the driveshaft.

  6. Limited-slip differential - Wikipedia

    en.wikipedia.org/wiki/Limited-slip_differential

    The clutch type has a stack of thin clutch-discs, half of which are coupled to one of the drive shafts, the other half of which are coupled to the spider gear carrier. The clutch stacks may be present on both drive shafts, or on only one. If on only one, the remaining drive shaft is linked to the clutched drive shaft through the spider gears.

  7. Clutch control - Wikipedia

    en.wikipedia.org/wiki/Clutch_control

    Clutch control refers to the act of controlling the speed of a vehicle with a manual transmission by partially engaging the clutch plate, using the clutch pedal instead of (or in conjunction with) the accelerator pedal. The purpose of a clutch is in part to allow such control; in particular, a clutch provides transfer of torque between shafts ...

  8. Continuously variable transmission - Wikipedia

    en.wikipedia.org/wiki/Continuously_variable...

    One disc is the input, and the other is the output. Between the discs are rollers, which vary the ratio and transfer power from one side to the other. When the rollers' axes are perpendicular to the axis of the discs, the effective diameter is the same for the input discs and the output discs, resulting in a 1:1 drive ratio. For other ratios ...

  9. Slipper clutch - Wikipedia

    en.wikipedia.org/wiki/Slipper_clutch

    One-way sprag clutches have also been used for the same purpose, but are generally not adjustable for disengagement force. Early Honda Shadow models used a design wherein a sprag clutch is connected to just half of the clutch friction plates, allowing the clutch to slip during heavy backloading sufficiently to prevent rear-wheel lockup, while ...
